Description
Technical field
The present invention relates to fertilizing method, more particularly to a kind of fertilizing method of alfalfa.
Background technology
Current vast Alfalfa Growing enterprise chemical fertilizer usage amount is big, and input is more, and fertilizer ratio is unreasonable, fertilization mode
Not science, the fertilizer amount material of input is big, and every mu of fertilising average input is 260~350 yuan, but alfalfa output is relatively low, every mu
Average product is 450~750kg.
The content of the invention
The present invention is intended to provide a kind of fertilizing method of alfalfa, to improve the yield of alfalfa.
The alfalfa fertilizing method of the present invention is as follows：
When clover turns green and grows into 15~30 centimeters, first round fertilising is carried out；
After clover cradles for the first time and when growing into 15~30 centimeters, the second wheel fertilising is being carried out；
After clover cradles for the second time and when growing into 15~30 centimeters, third round fertilising is carried out；
What the first round fertilising, the second wheel fertilising and third round fertilising applied includes yeast source organic fertilizer and growth period
Inorganic fertilizer, yeast source organic fertilizer is often taken turns using 5~20kg/ mus, and generation phase inorganic fertilizer is often taken turns using 5~20kg/ mus；
Fourth round fertilising is carried out after third time is cradled, the fertilizer of application includes yeast source organic fertilizer and formula of surviving the winter is inorganic
Fertilizer, yeast source organic fertilizer applies 5~10kg/ mus, and formula inorganic fertilizer of surviving the winter applies 3.33~10kg/ mus.
It is preferred that, in order to make fertilizer preferably be absorbed by alfalfa, the first round applies fertilizer, the second wheel applies fertilizer,
Third round fertilising is carried out in two times respectively, and interval time of applying fertilizer twice is respectively 7~10 days.
It is preferred that, in order to provide more rational proportion and sufficient nutriment, the yeast source to the growth of alfalfa
Organic fertilizer N P and K total content 10wt% (wt%, weight/mass percentage composition, similarly hereinafter) more than, more than content of organic matter 60wt% has
Imitate total viable count 0.2 hundred million/gram more than.
It is preferred that, more can be with suitable alfalfa in order to which the growth to alfalfa provides the inorganic fertilizer of more rational proportion
Required element is adapted during generation, and growth period inorganic fertilizer N-P-K content proportioning by mass is N:P2O5:K2O=(8~
14):(18~22):(19~26).
It is preferred that, in order to which the growth to alfalfa provides the inorganic fertilizer of rational proportion, and it is more beneficial for alfalfa
In the safe overwintering in winter, the formula inorganic fertilizer N-P-K content proportioning by mass of surviving the winter is N:P2O5:K2O=(5~6):
(19~22):(22~26).
It is preferred that, in order to obtain higher input-output ratio, the first round fertilising, the second wheel fertilising and third round are applied
In fertilizer, the fertilizer of application, yeast source organic fertilizer applies 6~15kg/ mus for often wheel, and growth period inorganic fertilizer total amount is that every wheel is applied
6~15kg/ mus.
It is preferred that, in order to obtain in higher input-output ratio, the fourth round fertilising, the fertilizer of application, yeast source has
Machine fertilizer applies 6~10kg/ mus, and formula inorganic fertilizer of surviving the winter applies 6~10kg/ mus.
It is preferred that, in order that alfalfa is more fully absorbed to fertilizer, it is more beneficial for the growth of alfalfa, institute
The dose twice for stating first round fertilising, the second wheel fertilising and third round fertilising is identical.
The alfalfa fertilizing method of the present invention is by rationally controlling when Fertilizer Type, dose, fertilizer application frequency and fertilising
Between, compared with using the alfalfa of traditional fertilization mode, the yield of alfalfa is added 15~30%.In addition, with
The fertilization mode of traditional alfalfa is compared, and every mu of input is also reduced, and improves input-output ratio.
